Abstract

The utility model relates to a mold of arbitrary demoulding type. The mold comprises a cavity plate and a core under the cavity plate. The core is arranged in the core plate. During demoulding, the cavity and the core plate are connected by a shutter. A base plate is arranged below the core plate, and an insert core is fastened on the base plate. The base plate is also provided with a pull rod and a spring by which the base plate and the core plate are connected. A support block is provided below the base plate, and a plurality of top plates are arranged inside the support block for fixing thimbles. The utility model can finish the demoulding of overturned products easily and securely by means of the mold structure.

Description

Mould structure

[technical field]

The utility model relates to a kind of mould structure, but and is particularly related to a kind of mould structure of forced stripper mechanism.

[background technology]

In the last few years, along with the extensive use of plastic product, the plastics industry had had the development of advancing by leaps and bounds, and had become indispensable important component part in the present industrial structure.As everyone knows, produce plastic product and will design corresponding mould structure, yet the internal structure of some plastic product is complicated unavoidably, as overhead kick treatment systems such as slide block, taper pins, desire wants pushing-off product must make finished product produce elastic deformation, produce the space that elastic deformation but must be out of shape, yet in the existing mould structure, eject at finished product and to go to toward can not giving the corresponding deformation space of finished product, cause finished product to be ejected, also just can not produce such as finished product with overhead kicks such as slide block, taper pins.

As from the foregoing, but in fact be necessary to provide a kind of mould structure that is ejected preceding forced stripper mechanism at finished product.

[summary of the invention]

But main purpose of the present utility model is to provide a kind of mould structure of forced stripper mechanism.

For reaching above-mentioned purpose, but the utility model provides a kind of mould structure of forced stripper mechanism, it comprises a caster, be provided with a mother module core in this caster, the below of mother module core is provided with a male model benevolence, described male model benevolence is arranged in the male model plate, and caster and male model plate be connected by a shutter when the demoulding, and the below of male model plate is provided with a backing plate, be fixed with one on the backing plate and go into son, and also be provided with a pull bar on the backing plate, and have a spring to cooperate pull bar that backing plate is connected with the male model plate, the below of backing plate is provided with foot pad, be provided with some top boards in this foot pad, in order to fixing thimble,, can safe ready ground realize the smooth demoulding of product overhead kick by above-mentioned mould structure.

Compared to prior art, but the mould structure of the forced stripper mechanism that the utility model provides is not only realized the smooth demoulding of product overhead kick but also simple in structure, cheap for manufacturing cost, workable, safe and reliable.

Fig. 1 is the generalized section of the utility model mould structure.

Fig. 2 is the demoulding step schematic diagram of the utility model mould structure.

[specific embodiment]

See also shown in Figure 1, generalized section for the utility model mould structure, the utility model mould structure comprises a caster 10, there is a upper mounted plate 900 top of this caster 10, and be provided with a mother module core 101 in this caster 10, the below of mother module core 101 has been provided with a male model benevolence 201, this male model benevolence 201 is arranged in the male model plate 20, and described caster 10 and male model plate 20 are connected by a shutter 3 when the demoulding, male model plate 20 and caster 10 when this shutter is used to be implemented in die sinking for the first time, the below of male model plate 20 is provided with a backing plate 30, be fixed with one on this backing plate 30 and go into son 301, this is gone into son 301 and arrives in the male model benevolence 201 by male model plate 20, and also be provided with a pull bar 40 on the described backing plate 30, and there is a spring 50 to cooperate pull bar 40 that backing plate 30 is connected with male model plate 20, backing plate 30 belows are provided with foot pad 60, be provided with in this foot pad 60 if in top board 70, in order to fixing thimble 701, foot pad 60 is fixed on the bottom plate 80 of below, and caster 10 is connected by a guide pillar 90 with male model plate 20 and backing plate 30 in addition.

See also shown in Figure 2, demoulding step schematic diagram for the utility model mould structure, during the demoulding, shutter 3 is held male model plate 20 and caster l0, so that male model plate 20 is connected motionless with caster 10, under self elastic force effect of spring 50, backing plate 30 drives son 301 motions, finish die sinking for the first time, when backing plate 30 drove son 301 and breaks away from finished product trip 7 fully, male model plate 20 and caster 10 overcame the binding force of shutter 3 under the active force of moulding board, finish die sinking for the second time, and this moment go into as can be seen the son 301 break away from finished product trip 7 fully after, then abdicated deformation space to finished product, then when male model plate 20 moves downward to a certain degree, thimble 701 pushing-off products, then trip 7 deforms under the extruding of male model benevolence 201, and forced stripper mechanism is finished smoothly.

Mould structure provided by the utility model is realized the sequential mold opening of three template dies with two template dies, just in public affairs Increase a backing plate between template and the foot pad, then by three template dies part lower link bar and shutter control commonly used Die sinking processed order, compared with prior art this use novel not only realize to the smooth demoulding of product overhead kick but also Has simple in structure, cheap for manufacturing cost, workable, safe and reliable advantage.

Claims
